The High Efficiency Particulate Air, or HEPA, filter, was created to keep scientists safe from radiation as they developed an atomic bomb during World War II. Today these filters are regularly used in hospitals, science labs and even homes.
HEPA filters are rated to remove 99.97 to 99.99% of particles measuring 0.3 microns and greater. This includes pollen, dirt and dust. A HEPA air cleaner with activated carbon filters can trap chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. This rating indicates how well a filter can clear pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are dense and can limit airflow. It’s important to ask Service Experts Heating & Air Conditioning to confirm your heating and cooling system can handle one.
Media air cleaners are denser than basic air filters. They’re often four to five times wider—or more. This barrier attaches snugly against your HVAC unit.
Because its operational surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters stay fresher longer too, usually between three to six months.
There are a couple of electronic filtering systems you can install in your home.
An electrostatic filter uses magnetically charged material to capture. These washable filters are 97 percent effective at clearing tiny particles from your home’s air. Plus, they’re also 30 times more effective than regular filters.
An electronic air cleaner uses a high-voltage magnetic charge to catch particles.
Some can eliminate the majority of indoor air pollutants—particles, germs, bacteria, chemical odors and vapors—by up to 99.9 percent. And minimize ozone, a known lung irritant, made elsewhere in your home.
